Description

technical field

[0001] The present invention relates to a (meth)acrylate, and in particular to a (meth)acrylate compound / oligomer with at least one end being a hydroxyl group and at least one end being an ethylenically unsaturated group. Background technique

[0002] Liquid crystal display devices have the advantages of light weight, power saving, no radiation and full-color display, and have become the most common display products at present.

[0003] With the development of display panel and touch technology, the requirements for adhesives necessary for fixing various parts in the display device are also getting higher and higher. For example, if an adhesive is to be used in the display area of ​​a display device, certain optical criteria must be met. In addition, stress will be introduced at the place where the adhesive is pasted, which may also affect the performance of the display device. Therefore, further research and improvement of current adhesives is necessary. ...
